Q

TIPS procedure

A

Transjugular intrahepatic potto systemic shunt.

Under conscious sedation, a stent is places percutaneously from right jugular vein into the hepatic vein.
Creates a connection between portal & systemic circulations.

Q

Endoscopic variceal ligation (EVL)

A

“Banding”
Involves application of small “O” bands around the base of the varices to decrease blood supply to varices.
Cause no discomfort and pt is unaware of band presence.

Q

Nurses role in paracenthesis

A
  • Explain, answer pt questions
  • obtain VS, including weight
  • ask pt to void prior to prevent injury to bladder.
  • position pt in bed with HOB elevated
  • measure drainage, record accurately
  • describe collected fluid
  • label & send them lab for analysis
  • after physician removes cath, apply dressing to site & apply pressure; assess for leakage
  • maintain bed rest
  • weigh pt after paracentesis; record.

Q

Functions of the liver

A
  • regulates composition of blood, including amount of glucose, protein, fat that enter the blood stream.
  • removes bilirubin, ammonia, and other toxins from blood
  • processes most of the nutrients absorbed by the intestines during digestion and converts nutrients into forms that body can use.
  • stores nutrients such as Vitamin A, iron, and other minerals
  • produces cholesterol, & proteins such as albumin
  • produces clotting factors
  • metabolizes alcohol & many drugs

  • perform “fluid wave” test
38
Q

Portal hypertension

A

Normal 3 mmHg

12mmHg= esophageal rupture

39
Q

Hepatic encephalopathy

Alteration in neuro status due to accumulation of ammonia

Build up of other substances such as hormones, GI toxins, other drugs

40
Q

Phases of Hepatin encephalopathy

A
  1. Onset: personality changes, disturbance of awareness, forgetfulness, irritability, & confusion.
  2. Second: hyperreflexia, asterixis, altered hand writing, violent, abusve behavior
  3. Coma: + babinski, hyperactive reflexes
41
Q

Cirrhosis nutrition

A
  • Low protein (sometimes), high carb, high cal-if signs of acute hepatic encephalopathy.
  • high carb, high protein, low salt
